Product details
Advantages and Characteristics
Aluminum foil composite film sampling bag
Aluminum foil composite film sampling bag is composed of multiple layers of polymer film and aluminum foil composite. This product has stable chemical properties and can store general industrial gases for a short period of time, ensuring constant concentration.
Aluminum foil composite film sampling bags can be used to collect percentages of hydrogen (H2), oxygen (O2), nitrogen (N2), methane (CH4), carbon monoxide (CO), carbon dioxide (CO2), industrial gases, petrochemical gases, environmental gases, and greenhouse gases.
The operating temperature for aluminum foil composite film sampling bags is -30 ℃ to+60 ℃.
The aluminum foil composite film sampling bag can be reused and needs to be cleaned with pure air or high-purity nitrogen gas.
We can customize sampling bags according to customer needs. For example: 5 milliliters to 500 liters.
We also provide aluminum foil paper and aluminum foil sample bags for packaging components.
Tedlar ® PVF sampling bag
Tedlar ® The PVF sampling bag is made of polyvinyl fluoride (PVF) film produced by DuPont in the United States, with a thickness of 50 microns. This product has excellent chemical resistance, solubility resistance, pollution resistance, and resistance to strong acids and alkalis. At room temperature, it is not affected by conventional solvents.
Tedlar ® The PVF sampling bag can collect carbon monoxide (CO), sulfur dioxide (SO2), hydrogen sulfide (H2S), benzene, radon and thiols, hydrocarbons, and chlorinated solvent gases. Suitable for short-term storage of low concentration (ppm, ppb level) corrosive gases and chemically active gases (for pre saturation treatment). Collection of photosensitive compounds and halogenated volatile organic compounds (VOCs).
If containing ppm or ppb level active compounds, high-purity nitrogen should be used to clean the sampling bag to reduce the influence of background. The sampling bag can also be placed in an oven and heated at 40 ° C to 60 ° C to weaken the influence of the background.
Tedlar ® The PVF sampling bag is applicable to the national environmental protection standards HJ 732-2014 "Sampling Bag Method for Volatile Organic Compounds in Fixed Pollution Source Exhaust Gas" and HJ 38-2017 "Determination of Total Hydrocarbons, Methane, and Non Methane Total Hydrocarbons in Fixed Pollution Source Exhaust Gas by Gas Chromatography" of the People's Republic of China. If the US EPA analysis method is used, it is suitable for dissolution experiments (TCLP), TO-3 (VOCs), TO-12 (NMOC), TO-14A (VOCs), TO-15 (VOCs), ASTM D-5504, and other various atmospheric gas collection methods.
In Tedlar ® Cover the PVF film material with a layer of black plastic or aluminum film to avoid light and prevent sample degradation.
.Tedlar ® The usage temperature of PVF sampling bags is -72 ℃ to 107 ℃.
We can customize sampling bags according to customer needs. For example: 20 milliliters to 4000 liters.
The valve accessories we provide are used for Tedlar of various sizes ® PVF sampling bag.
We also offer Clip-n-Seal ® Sealing strip, used for holding solid objects in bags, such as car interior decorations and components, rail transit interior decorations, plants, etc.
Teflon ® FEP sampling bag
Teflon ® The FEP sampling bag is made of polytetrafluoroethylene (FEP) film produced by DuPont in the United States, with a thickness of 50 microns.
Teflon ® The main features of FEP sampling bags are:
High transmittance, targeting ultraviolet and other rays, except for far-infrared radiation
High strength impact resistance, wear resistance, tear resistance
Anti adhesive and low friction properties
Resistance to dissolution and pollution, resistance to strong acids and bases (excluding molten alkali metals, fluorine gas, halogenated compounds at higher temperatures and pressures)
Has low permeability to liquids, gases, moisture, and organic vapors
Teflon ® The usage temperature of FEP sampling bags is -240 ℃ to 205 ℃.
Teflon ® The FEP sampling bag is applicable to the National Environmental Protection Standards of the People's Republic of China HJ 732-2014 "Sampling Bag Method for Volatile Organic Compounds in Fixed Pollution Source Exhaust Gas" and HJ 38-2017 "Determination of Total Hydrocarbons, Methane and Non Methane Total Hydrocarbons in Fixed Pollution Source Exhaust Gas by Gas Chromatography".
